Process plant operate by using many sophisticated process control systems. These systems are required for the safe and reliable operation of the plant and address safety functions such as process sectioning, fire and gas detection, process protection and blow down. These safety functions are often designed by combining various E/E/PES technologies and other external risk-reducing devices. In addition, computer and software intensive systems are increasingly being used as part of the system.
VAIL-SIL is a software product that uses the Safety Integrity Level (SIL) method as VELOSI’s methodology for monitoring safety critical systems. Safety Integrity Level (SIL) is a discrete level for specifying the safety integrity requirements of the safety functions to be allocated to the E/E/PE safety related systems. E/E/PES is a term introduced by the IEC61508 standard, which stands for Electrical, Electronics and Programmable Electronics Systems.
Various methodologies are available for the assessment of target SILs. VELOSI has implemented three different methodologies in our system:
Furthermore, VAIL-SIL is not limited to just calculating target SILs; among others, it also includes:
By utilizing VELOSI’s SIL managing techniques and software, you can optimize the management of your safety critical systems and implemented protective functions in line with the industry’s best practices without compromising safety.
